Answer

The total weight of the Hamilton circuit is 70.

Work Step by Step

To find the total weight of the Hamilton circuit, we can simply add up the weight of each edge in the circuit.
The Hamilton circuit is A,D,B,C,A. So the edges that are used in the Hamilton circuit are AD, DB, BC, and CA.
The weights of these five edges are 14, 12, 24, and 20.
total weight = 14 + 12 + 24 + 20
total weight = 70
The total weight of the Hamilton circuit is 70.
